Sir: Transcranial magnetic stimulation (TMS) is a noninvasive method for stimulating predefined areas of the cortex. It not only is used as a neurologic technique to measure connectivity and excitability of the cortex by magnetic stimulation, but also has clear effects if added to the standard treatment of psychiatric diseases.1,2 The activation of neural tissue by TMS is not limited to the stimulated cortical area but can also spread to connected intralateral and contralateral structures.3
